Answer:
False
Explanation:
The histones that are more positively charged, tight hardly to negatively charged DNA. So, enzymes, such as acetyltransferases, that reduce the positive charge of histones promote transcription.
Chromatin structure and its modifications can change the package of the DNA and consequently, alter the gene expression. The most common modifications of the chromatin are covalent modifications such as acetylation/deacetylation (by acetyltransferases and eacetylases), methylation (by methyltransferases), and phosphorylation (by kinases). This is the way of gene expression regulation.
The effects of modifications are different, for example methylation promotes condensation of the chromatin and as a consequence, prevents binding of transcription factors to the DNA (transcription is repressed).
Acetylation loosens the association between nucleosomes and DNA (because it neutralizes the positive charge of histones) and consequently promotes transcription. Deacetylation is a process opposite to acetylation.
Answer:
Land restoration can include the process of cleaning up and rehabilitating a site that has sustained environmental degradation, such as those by natural cause (desertification) and those caused by human activity (strip mining), to restore that area back to its natural state as a wildlife home and balanced habitat.
Explanation:
- setting up reliable water provisioning (e.g. by digging wells or placing long-distance water pipes)
- stabilizing and fixating the soil
Business Impact Analysis
Business Impact Analysis (BIA) refers
to the method of determining the potential risks that a business will encounter
when disaster strikes. It is the first step in the contingency planning process.
Large businesses with strong disaster recovery planning programs put BIA into
their programs, making it one of the important stages. Unless BIA has been
conducted, the disaster recovery programs will not be fully developed since the
output of BIA will ascertain the strategies and policies that will be in the
disaster recovery program of the company.
